Logging atoms shouldn't stringify request time seconds/microseconds

[estebistec]

Looking at [1], we see that the seconds and microseconds attributes of the request-time timedelta are run through str.

This is a problem because access_log_format should technically be able to use the full range of Python string-formatting options [2], where applicable by type. For the request-time attributes, this means we should be able to format with %d in addition to %s, but the early conversion to string prevents this.

Simple fix is to remove the call to str(), allowing either a simple %s formatting or %d with all available Python string-formatting options. For example, to work around #584 one should be able to say "%(T)s.%(D)06d".

Pull request forthcoming.
